Title: Transmitting and receiving antenna separation type underground searching radar
Inventor: TANAKA HIROAKI
IPC: G01S7/02
Filed: 1985-06-25
Abstract: PURPOSE:To facilitate the discrimination of a reflected wave, by respectively covering transmitting and receiving antennae with a metallic shield case and electrically coupling the same with a shield case and eliminating the superposition of the reflected wave from an objective target and an unnecessary radio wave. CONSTITUTION:Transmitting and receiving antennae 1, 2 are respectively separately covered with metal shield cases 3, 4 which have ferrite radio wave absorbing bodies 7, 8 for preventing inner surface reflection respectively adhered to the insides thereof and the side surfaces of the outside metal plates 5, 6 of both shield cases 3, 4 are contacted to electrically connect said shield cases 3, 4. Therefore, the direct wave from the transmitting antenna 1, the reflected wave from the surface of the ground or an external radio wave is absorbed by the shield cases 3, 4 to be prevented from entering the receiving antenna 2. By this method, the reflected wave from an objective target and an unnecessary radio wave are not superposed on each other and the discrimination of the reflected wave from the objective target becomes easy.
